Some of the most catastrophic injuries victims can sustain in car accidents are facial fractures, including orbital blowout fractures. The most common type is an open door fracture. This is also the most serious and involves the complete devastation of the orbital socket. The eye socket appears larger than normal and the eyeball will appear sunken back into the socket. The victim usually suffers from double vision, as well as a complete loss of feeling around the socket. This is because the infraorbital nerve is also destroyed in this type of fracture.

A trap door fracture is less common and is usually seen in children. The break is minimal, although the infraorbital nerve is also damaged in this type of fracture, leaving the victim with a loss of feeling around the cheek.
